| Abstract:This paper proposes an appropriate way for the transformer connection in the grid-connected photovoltaic system through simulation and experiment. First，the isolation transformer and its function are briefly discussed and a theoretical analysis on resonance over-voltage， fault detection and harmonic are conducted. The basic principles on the selection of the photovoltaic grid system isolation transformer are identified. Second， the data obtained through Matlab simulation and experiment is analyzed. The results show that a more appropriate way of transformer connection should be the Δ/Yn mode in the single-stage grid-connected system. The study in the paper can provide some references for the development of the large-capacity photovoltaic power plant. |
